STORAGE-BATTERY CELL.

Specification 01' Letters Patent.

Patented Sept. 22, 1914.

Application filed March 14, 1911. Serial No. 614,425.

vide for opposing leakage by reason of splash or spray throu h the filling opening.

The invention will e claimed at the end hereof but will first be described in connec tion with the embodiments of it chosen for illustration in the accompanying drawings in which Figure 1, is a top or plan View of a storage battery cell embodying features of the invention. Fig. 2, is a transverse sectional view of the upper part of the cell, and Figs. 3, 4 and 5, are perspective views of channel members embodying modifications of the invention and detached from the cover of the cell.

In the drawings 1, is a tell-tale surface arranged opposite the filling opening 2, and contrasted with the surface of the fluid in the cell, which surface is indicated by the dotted line 33. The tell-tale surface may be contrasted with the fluid surface by roughening or interrupting it andit maybe so roughened by 'provlding it with perforations 4, as shown in Fig. 8, or with projections 5, as shown'in Fig. 4, or with'ribs or corrugations 6, as shown in Fig. 5. The

object is to provide a surface which will show when the level of the fluid reaches it and this surface may therefore be considerably modified while still accomplishing that pur ose. The channel member of which the sur ace 1, is the web portion also comprises arm portions 7, and side portions 8, by means of which the web portion 1, is spaced away from the arm portions 7. The arm portions 7 are applied to the under side of the cover 9, and the channel member may range crosswise of the cover and of the applied. to the cover and its Web plates 10, so that its 0 en ends are disposed toward the longer sides of the cell. The channel member not only presents the telltale or distinguishing sition opposite the filling opening but it also opposes splashing and spraying toward that opening and thus opposes leakage. What I claim is:

1. In a storage battery cell the combination of a cover having a filling opening and a channel member applied to the cover with its web portion spaced from the cover and arranged opposite the opening to operate as a tell-tale in filling the cells.

2. In a storage battery cell the combination of a cover having a filling opening and a channel member applied to the cover with its web portion roughened and spaced from the cover and arranged opposite the opening to operate as a tell-tale in filling the cell.

3. In a storage battery cell the combination of a cover having a filling opening and a. channel member applied to the cover withv its webportion per orated and spaced from the cover and arranged opposite the opening to operate as a. tell-tale in fillin the cell.

4. In a storage battery cell t e combination of a cover-having a filling opening and a channel member having its arm portions applied to the cover and its web ortion spaced from and arranged op oslte the opening, substantially as describe 5. In a stora e battery cell the combination of a cover aving a filling opening and a channel member having its arm portions ortion spaced from and arranged opposlte the opening and its open ends dis osed toward the longer sides of the cell, su described. 1

6. In a storage battery cell the combination. of the plates thereof, the electrol te, and a. telltale or distinguishing sur ace maintained in a fixed position above the plates as a ga e for fixing the level of the electrolyte in ling the cell.

In testimony whereof I have hereunto stantially as signed my name.
